Our Verdict
ASUS ROG Strix XG27UQ
Gigabyte M28U
The ASUS ROG Strix XG27UQ and the Gigabyte M28U are very similar overall, but the ASUS is slightly better for most people, as it has better ergonomics. The Gigabyte has slightly better reflection handling, and its black frame insertion feature is a bit more versatile, as it works across a wider range of refresh rates.
